Chinese energy storage system supplier CNTE has installed a 700kW/1.624MWh battery energy storage system at an industrial facility in Schwabmünchen, Germany.
The system integrates the unnamed factory’s existing 440kWp solar photovoltaic array, 500kW diesel generator and grid connection into a hybrid power system.
CNTE installed seven of its liquid-cooled STAR-H units, each rated at 100kW/232kWh. Its energy management system coordinates the battery, solar generation, grid supply and diesel generator according to demand at the site.
The company said the Germany installation was designed to increase solar self-consumption, reduce inefficient operation of the diesel generator at low loads and maintain continuity of supply for factory production.

CNTE estimates the system could deliver additional energy-cost savings of about €27,000 ($32,000), based on the project assumptions and annual solar generation of approximately 449MWh.
In a modelled two-hour grid outage, it said using the battery alongside the existing backup system could save approximately 254 litres of diesel, worth around €570. CNTE did not disclose the German factory operator or provide measured operating results from the installation.
The company frequently describes itself in English-language announcements as “invested by CATL”. Corporate disclosures show CATL is a minority investor rather than CNTE’s parent company.
A CATL filing records a 20% holding in CNTE. A separate shareholder disclosure listed CNTE’s largest shareholder as Fujian Jizhi Energy Storage Technology, with 35%. That company was 90%-owned by Huang Shilin at the date of the filing.
Huang, CNTE’s chairman, was one of CATL’s founders and previously served as its vice-chairman and general manager. He was still a senior CATL executive when CNTE was established in 2019.
The remaining disclosed shareholders included CNTE general manager Shi Zhengping with 20%, battery test equipment manufacturer Nebula Electronics with 10%, and two investment partnerships with 7.5% each.
CNTE supplies battery systems for residential, commercial and industrial, and utility-scale applications. Its STAR-H cabinet uses lithium iron phosphate cells and is designed for solar integration, peak-load management and backup power.
